Abstract :
Perovskite nanoparticles La1-xSrxMnO3 were successfully synthesized by modified sol-gel method. Their structure and magnetic properties were systematically investigated in dependence on doped Sr ratio x. The structure was investigated by X-ray diffraction and showed a slight change, but magnetic properties varied strongly with changing x. Magnetic properties of samples studied by physical property measurement system show spin-glass behavior with Curie temperature and blocking temperatures above room temperature. The blocking temperature as well as Curie temperature varies by changing x. At room temperature, the samples show superparamagnetic properties with high saturation magnetization MS up to 87 emu/g, which strongly depends on the doped Sr ratio x.
